I think it would take 18 months to drive round the earth 15 years to drive too the moon 25 years too venus 65 years too the sun 100 years to pluto

Kaden, Greytown
I think it would take 2 years to drive around the world 20 years to drive to the moon 40 years to drive to Venus 80 years to get to the sun 120 years to Pluto

Madison, Greytown
I think it would take 1 year to drive round the earth 5 years to get to the moon 12 years to get to venus 30 years to get to the sun 100 years to get to pluto


I think it would take 10 months to drive around the world 3 years to get to the moon 4 years to get to Venus 8 years to drive to the sun 20 years to get to Pluto.


 I think it would take 6 months to drive around the world 1 year to get to the moon 1 year and 6 months to get to Venus 5 years to drive to the sun and 10 years to get to Pluto.

However, as we all know, you can't exactly drive to pluto, you'd have to take a rocket. And if you traveled to Pluto in a rocket I'm guessing it would take three or four months.

If I was traveling in a car a 100kmph how long do I think it would take to travel.... Around the earth= 1 year and 2 months To get to the moon= 3 years and 7 months Venus(our nearest planet)= 8 years and 4 months The sun= 15,000 years and 6 months Pluto= 246,396 years and 3 months

If I was traveling in the fastest rocket known to man( it goes 40,000kmph) how long do I think it would it take to travel....... Around the earth= 1 hour To get to the moon=3.5 hours Venus(our nearest planet)= 18.3 hours The sun=259days and 6 hours Pluto= 1 year and 354 days

<span style="color: rgb(8, 7, 7)">Put your answers after each section. <span style="color: rgb(8, 7, 7)">The Outer Planets Throughout most of human history, only six planets have been known: Mercury, Venus, Earth, Mars, Jupiter, Saturn. (Most of the time nobody knew what planets were or that the Earth is a planet.) Then, in the last three centuries, three new planets were discovered. Uranus, though theoretically visible to the naked eye on fine nights if you know just where to look, was not noticed till 1718. Neptune was discovered by careful calculation and search in 1846, and Pluto in a similar way, but not till 1930 after a quarter of a century of meticulous search, for even in large telescopes it is lost among countless thousands of equally faint stars. <span style="color: rgb(8, 7, 7)">And anyone who takes your planet-walk will say: "No wonder!" The Moon On our scale model the moon is about 5.5 centimetres from the Earth. Using the model put a moon down beside the Earth. This Moon will have to be another pinhead (theoretically between the sizes of Mercury and Pluto). Look down on this distance, the length of your thumb. This is the greatest distance that Man has yet leaped from home. Reflect on the manned mission to Mars now being suggested (14 paces / metres in our model) or the trips proposed in science fiction: to Jupiter as in the film 2001 Space Odyssey (109 paces); to the nearest star (seven thousand kilometres in our model); to the Andromeda Galaxy (half a million times farther again). __<span style="color: rgb(248, 13, 13)">Find out some information about manned trips to the moon. __ *

<span style="color: rgb(8, 7, 7)"> <span style="color: rgb(8, 7, 7)">Greater Distances The solar system does not really end with Pluto. Besides the planets, there is a thin haze of dust (some of it bunched into comets). Any of this dust that is nearer to the Sun than to any other star may be held in the gravitational field of the Sun and so counts as part of our solar system. So the outermost edges of this may be half way to the nearest star. On the scale of our model, Pluto is one kilometre out. But the true limit of the solar system (in our model) is four thousand kilometres out. How far away is that? There is a lot of nothing out there especially if we think of it as a very large ball. __<span style="color: rgb(244, 11, 11)"><span style="color: rgb(246, 9, 9)">Do some research on the Oort cloud __ You might start here http://en.wikipedia.org/wiki/Oort_cloud

<span style="color: rgb(8, 7, 7)">The Emptiness of Space It is hard to understand how the sun’s gravitational attraction holds the planets in orbit over such huge distances. Mainly this is because in our model there are all sorts of other things, buildings, trees, people etc. In space there is NOTHING – it is empty pretty much. It is only because space is so empty that the Sun is the nearest important gravitational influence on the Earth. __<span style="color: rgb(234, 11, 11)">Write your wonderings? __ * toc

How far have things gone?
Have a think about space travel. What would you need? Where might you head? Why? Have a look at http://imagine.gsfc.nasa.gov/docs/ask_astro/answers/980224b.html http://en.wikipedia.org/wiki/Voyager_1 and think about it. Why does it take 14 hours for the signals to reach Earth? What would it be like if you were light years away?
